Read the excerpt from The Code Book. Other attacks include the use of viruses and Trojan horses. Eve might design a virus that i

nfects PGP software and sits quietly inside Alice's computer. When Alice uses her private key to decrypt a message, the virus would wake up and make a note of it. The next time that Alice connects to the Internet, the virus would surreptitiously send the private key to Eve, thereby allowing her to decipher all subsequent messages sent to Alice. One way to better connect with this excerpt is to

Answer:

Tell about an experience with a computer virus.

Explanation:

Simon Singh's "The Code Book," tells the history of how cryptography came into being and the secret messaging world of encryption. Through the detailed narration and diving into the history of encryption, the author traces the evolution of such a process and reveals how it has had a huge impact on the world's policies.

In the given excerpt, Singh gives an example of how viruses are planted and used to spy/ get access to other people's computers. But while it is possible to get the main point of the example, <u>it would have been better if the writer includes experience with a computer virus</u> so that readers will find it easier to connect with the given example. This will enable them to better understand the working of viruses and their effects.

Thus, the correct answer is the first option.

Murrr4er [49]

Answer: car | truck

Explanation: The pipe (|) symbol used can be used in regular expression to simply imply OR. This means when used in between expression, can be used to search for all matches of the strings in which it stands in between. In the scenario above, If the pipe symbol is located in between the two strings, such as [ cars | trucks], the expression returns possible occurrence of the strings cars and trucks. It may also be used to locate and return the occurrences of more than 2 strings, such as; string1 | string2 | string3

Program 7 - Circle You write ALL the code, then run it - Produce the correct output. Turn in code and screen print of successful
fgiga [73]

Answer:

Here is the Circle class:

public class Circle {   // class definition

private int radius;    // private data member of type int of class Circle named radius that stores the value of radius

public Circle(int r) {   // parameterized constructor of class Circle that takes radius as argument

 radius = r;  }    // sets value of radius as r

public int getRadius() {   // accessor method to get the value of radius

 return radius;  }   // returns the current value of radius

public int Diameter() {   // method to compute diameter of a circle

 return radius * 2;  }   // multiply radius value by 2 to compute diameter of Circle

 

public double Area() {   // method to compute area of a circle

 return Math.PI  * Math.pow(radius, 2);   }   //the formula of area is

π x radius² where value of π is get using Math.PI

 

 public double Circumference() {   // // method to compute circumference of a circle

 return 2* Math.PI * radius;   }   }  //the formula of circumference is

2 x π x radius where value of π is get using Math.PI

Explanation:

Here is the Main class:

import java.util.Scanner;  //to accept input from user

public class Main {  //definition of Main class

public static void main(String[] args) {  //start of main method

   

    Scanner scanner = new Scanner (System.in);  //creates Scanner object to take input from user

    System.out.println("Enter radius: ");  //prompts user to enter radius

    int r = scanner.nextInt();  //reads the value of radius from user

 Circle c = new Circle(r);  // calls Constructor of Circle passing r as argument to it using the object c of class Circle

 

    if(c.getRadius()<=0){  //calls getRadius method to get current value of radius using objec and checks if this value (input value of r ) is less than or equal to 0

        System.out.println("Error!");   }  //when above if condition evaluates to true then print this Error! message

    else {  //if the value of radius is greater than 0

System.out.println("the radius of this Circle is: " +c.getRadius());  //calls getRadius method to return current value of r (input value by user)

System.out.println("the diameter of this Circle  is: " + c.Diameter());  //calls Diameter method to compute the diameter of Circle and display the result on output screen

System.out.printf("the circumference of this Circle  is: %.2f", c.Circumference());  //calls Circumference method to compute the Circumference of Circle and display the result on output screen

System.out.println();  //prints a line

System.out.printf("the Area of this Circle  is: %.2f", c.Area()); } }  }

//calls Area method to compute the Area of Circle and display the result on output screen

The program and its output is attached.
